I wish to add a utility sink to my basement. There is a working sump pump very close. To save cost and time can I run my drain to this sump rather than through finished walls and to the main stack? It will surely cause the pump to run but only on occasion when I wash something like my hands or washing some dishes. Does it run the risk of getting clogged?
Just drill a hole into the plastic lid and add my drain?
Thanks !

Is this a sump pump or a sewage ejector unit? Do you have fixtures in the basement already draining into it? How many pipes are coming out of the pit?
I don't believe a sump pump will handle a washer discharge. A sump pump's designed to pump out clear water that collects in the pit. Your asking it to handle soapy water, the grease from the soap and all the fiber that a washer produces and I'm not sure it's up to the job. Besides if the pit's not sealed it will began to smell in time. Your best bet would be to vent the washer and connect to the main stack. Or if there's a floor drain handy you could run a indirect waste to it. Good luck, Tom

I would advise you against drilling hole into the lid no matter if it is sump-pump or sewer ejector.

Sorry! I assumed you would be discharging a washer into the sink

It only has one line coming out and nothing going into it except the electric line to power it and the battery backup.

Is there a floor drain in your basement? Tom
